... ok, so it's a DVI monitor. Any way you could test with a VGA
adaptor?
Also, does X work ( with an updated radeon driver ) ? Doesn't matter if
it's on top of genfb or radeonfb, it should Just Work without any
config file hackery. I tried to replicate their Mini workarounds in
radeonfb, I'd like to know if the original works before looking into my
copy.
